" Application filed May 19,

To allwhom it may comm;-

Be it known that I, LEWIS DICKINSON, a citizen of the United States of America, residing at Jacksonville, in the county of Duval and State of Florida, have invented new and useful Improvements in Hammers, of which the following is a specification.

The object of the invention is to provide a construction of hammer whereby it is adapted to be used as a substitute for a mallet or maul in the operating of a chisel or similar tool without causing the battering or damaging of the chisel handle as ordinarily caused by the impact therewith of a metal hammer pole; and furthermore to provide a means for the purpose indicated which may be applied to or formed in connection with 'an ordinary hammer head without in any way detracting from or modifying the utility of the hammer for other purposes,'and without involving the addition of any appreciableweight thereto or causing such a projection from the ordinary outlines of the hammer head as may serve to interfere with the uses to which the hammer is ordinarily applied; and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the'drawing wherein:

Figure 1 is a side view of a hammer head provided with the attachment. 7

Fig. 2 is a plan view of the same.

Fig. 3, is a sectional view on the plane in- V dicated by the line 33 of Fig. 2.

Fig. 4, is a sectional view on the plane indicated by the line 44 of Fig. 1.

Fig. 5, is a detail in perspective of a retaining band preferablyvused in connection with the impact block.

Fig. 6,. is a plan view of a hammer head showing in section a modified construction and mounting of the block.

Fig. 7 is a side view of the construction shown. in Fig. 6.

The hammer head 10 which may be of the ordinary or any preferred form, preferably having the usual pole 11 and-claw 12 ispro-' vided at its central eye portion with a lateral flange 14 inclosing a shallow seat 15 adapted for the reception of a block 16 of wood, rubber or composition of moreor less yielding orspringy material adapted to be used in drivinga chisel orin striking the handle portion of a similar tool without causing the breakdown or marring of the fiber of such 7 I I Specification of Letters Patent.

handle as is ordinarily, caused by the contact therewith of a metal driving implement.

In the preferred construction, the flange 14 entirely incloses the seat which may be rectangular as shown and the inner surfaces of the flange are perpendicular to'the bottom or floor of the seat to receive a rectangular block which is held against displacement in a direction perpendicular to the seat by means of set screws 17, extended through the flange and adapted for terminal engagement with the block. As a further means of reinforcing the block, as indicated in Figs. 1 to 4 inclusive, there is provided a band 18 of sheet metal or its equivalent, split as indicated in Fig. 5 to facilitate its application to the block 16 and provided with an inturned flange 19 which engages a groove 20 formed in the side surfaces of the block. Obviously the reinforcing band should be applied to the block before the latter is fitted in the seat after which the tightening of the set screw 17 will securely lock the parts in position and prevent incidental displacement in the use of the tool.

The block is preferably enlarged at its outer side as shown at 21 to overlap the flanges of the reinforcing band and also the edges of the flange 14 so that the latter serves to prevent the objectionable deflection of the edge portions of said enlargement.

In the modified construction illustrated in Figs. 6 and 7, the impact block 22 is cross sectionally dovetailed for engagement with the elongated inner surfaces of the flange 28 also provided with set screws 24, the seat formed by said flange being open at one side as indicated in Fig. 4 to permit of the block being slid into engagement with the seat in a plane parallel'with the seat on the hammer .head 25. In this form of the device, as in the preferred form above described, a reinforcing band'26 may be fitted around the seated portion of the block.

Obviously the block may be replaced from time to time as required and owing to the lightness thereof and the apparent shallowness of the retaining flanges, this attachment adds but little to the weight of the hammer head and does not serve to destroy the balance thereof so that for ordinary purposes the hammer head is not modified as to utility.

Inasmuch as the supplemental impact face represented by the block is located at the turn the tool in the hand slightly in order to bring the sameinto operative positions and the Weight of the head serves to enable the;

operator to apply an impact of the required force to the handle of the tool to be driven. The invention having been described, What is claimed'asnew anduseful is L 1. A hammer head having a side seat, a cushioned impact block removably fitted in said seat and a split reinforcing band em bracing the block within theseat and set screws carried by the walls of the seat for impiingement at their inner ends against said ban j 2. A hammer head having aside seat, a 'cushionediinpact block fittedin said seat, a split reinforcing band embracing the block LEWIS DICKINSON. V
